To be honest they are comic humans and do not have any significant similarities to real humans whatsoever than appearance and common language. Their durability/strength is superior, magic exists and is controlled by them and their intelligence is greater than any force except when it is shut off for plot or vice versa. The irony here (and it is staggering) is comic humans share more in common with superman than any one that can ever be a real human. Their humanity is the largest joke hiding in plain sight in all of comics much like superman's identity.
All the characters mentioned i have the highest respect for btw...
